Cakes Are To Moist?

Hi all, i just made 6 cakes to freeze, now that they are froze and were completey cooled they seem flatter , when i unwrap them they feel wet on the bottom, kind of sticks to the saran wrap, also when i go to level them even with a sharp knife it doesn't go through smoothly, what am i doing wrong, thanks

I level the cakes before I freezer them.1) easier to stack if they're flat.2) easier to do any final trimming on a partially frozen cake.

I work with the cakes when they are still partially frozen.1) easier to lift and stack, especially the larger layers.2) easier to ice as the cake is not all super-moist and gooey as a totally thawed cake.
